The Nemo Xo Carbon 308Win 20" precision tactical rifle is a lightweight, modular AR-platform carbine built for shooters who demand accuracy and versatility without sacrificing portability. This is a purpose-built rifle for precision work at distance—whether you're running drills at the range, hunting mid-range game, or setting up for tactical applications. At 8.2 pounds unloaded and 38.5 inches collapsed, the XO carbine proves that a serious .308 doesn't have to be a burden to carry or mount.
Nemo Arms engineered the XO around a Proof Research 20-inch carbon fiber barrel with a 1:10 twist, optimized to extract velocity and consistency from .308 Winchester loads. The billet 7075-T6 and 7076-T6 aluminum receiver set is hard-anodized in tungsten grey and paired with a patented recoil reduction carrier and tuned buffer system—features that add up to reliable, softer-shooting performance. The dual-chamber titanium muzzle brake can be tuned for suppressed or unsuppressed fire, and the extended-length gas system pairs with a quick-switch gas block for flexibility. Ambidextrous controls throughout—safety, charging handle, and upper/lower receiver—make the rifle equally at home in a right or left-handed shooter's hands.
The trigger is a Geissele Super Dynamic Enhanced two-stage unit tuned for precision work, while the 15-inch M-LOK rail gives you mounting real estate for optics, lights, and accessories. Magpul furniture—CTR stock, MIAD grip, and a 20-round P-Mag—rounds out a rifle that's ready to run. This is a serious performer for the shooter who values efficiency, control, and the ability to stretch shots without the weight penalty of a full-length platform.
